Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Sony A7R III and Fujifilm GFX 100 side-by-side from the front, back and top in their relative dimensions.
Below you can see the front view size comparison of Sony A7R III and Fujifilm GFX 100. Sony A7R III is clearly the smaller of the two cameras. Its body is 29mm narrower, 48mm shorter and 1mm thinner than Fujifilm GFX 100.
Here is the back view size comparison of Sony A7R III and Fujifilm GFX 100.
Now lets look at the top view comparison of Sony A7R III and Fujifilm GFX 100.

LCD Screen Size and Features
Fujifilm GFX 100's 3.2x LCD screen is slightly larger than Sony A7R III's 3" screen.
Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Fujifilm GFX 100 has a 102.0MP Medium format (44 x 33 mm ) sized BSI-CMOS sensor and features X-Processor 4 processor.
Fujifilm GFX 100's sensor provides 60MP more than Sony A7R III's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Another difference between these two cameras is that Sony A7R III's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.
